工作中用到播放视频时，需要横屏将视频全屏播放，所以需要监听屏幕的横竖屏切换事件。
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
if (player != null) {
player.onConfigurationChanged(newConfig);
}
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
llyBottom.setVisibility(View.GONE);
Toast.makeText(getApplicationContext(), "横屏", Toast.LENGTH_SHORT).show();
} else {
llyBottom.setVisibility(View.VISIBLE);
Toast.makeText(getApplicationContext(), "竖屏", Toast.LENGTH_SHORT).show();
}
}
